Colapteroblatta compsa Hebard, 1919

Figs 8-9, 85-105

Material examined: MHNG; 1 male; N. Colombia, Dept. Magdalena, N. Sierra Nevada de Sta. Marta, San Lorenzo , 2200 m; 18.- 24.08.1985; coll. H.G. Müller, “am Wegrand, aus der Vegetation” . – MHHG; 1 female; same data as for the male, but 22.08.1985, “am Wegrand, unter Stein” .

Remarks: The original description ( Hebard, 1919) and the data of Roth (1971) and Roth & Gutierrez (1998) are sufficient and a re-examination of the types is therefore not necessary. The type material (not examined) is probably kept in entomological collection of Academy of Natural Sciences of Drexel University (former Academy of Natural Sciences of Philadelphia). The type locality is “San Lorenzo, Sierra Nevada de Santa Maria, Magdalena, Colombia ” ( Hebard, 1919), i.e. the specimens redescribed below were collected not far away from the type locality. The following supplementary details can be given.

Somatic characters of male: General colour yellowish brown. Colouration of head as in Fig. 8, eyes black, facial part of head with large longitudinal dark brown spot. Antennae yellowish brown. Central part of pronotum dark brown, lateral part yellow ( Fig. 86). Surfaces smooth and lustrous; head with transverse wrinkles ( Fig. 85); head, pronotum and costal field of tegmina with distinct punctuation. Head longer than wide, vertex projected between eyes, with indistinct transverse impression between antennal sockets ( Figs 8, 85); ocellar spots large; distance between eyes 0.8 times eye length; distance between antennal sockets about 0.5 times scape length (~ 1.2 mm); approximate length ratio of 3rd-5th segments of maxillary palps 1.3: 1.0: 1.2. Pronotum rounded, with hind margin weakly projected ( Fig. 86). Tegmina and wings completely developed, strongly elongated, surpassing abdominal apex. Tegmina membranous, only proximal part of costal field slightly sclerotized; apex rounded; venation distinct; costal field short and narrow; Sc thickened (well visible on ventral side of tegmen); R, M and CuP basally fused. Wings membranous. Fore tibiae not thickened distally. Anterior margin of fore femora of armed type C, with single apical spine. Tibial spines well developed. Structure of hind tarsus ( Fig. 87): metatarsus distinctly shorter than other tarsal segments combined, with large euplantula; spines absent; claws symmetrical, simple; arolium distinct, about half as long as claw. Fore and mid tarsi similar to hind tarsi but segments comparatively shorter. Abdomen without visible glandular specializations; spiracle-bearing outgrowths of tergite VIII without attenuate posterolateral angles ( Fig. 88). Anal plate (tergite X) with widely rounded hind margin with weak medial incision ( Fig. 88). Cerci slender, with distinct segments ( Fig. 88). Paraprocts of blaberid-type ( Fig. 89). Hypandrium asymmetrical, hind margin between styli projected and rounded ( Fig. 90); styli short, cylindrical and asymmetrical: right stylus about twice as long as left stylus ( Fig. 90).

Male genitalia ( Figs 91-98): Right phallomere (R+N): caudal part of sclerite R1T well sclerotized, dorsally with “upper triangular lobe” ( Fig. 91, tr.l.), this lobe and adjacent membranes covered with bristles; R2 short and nearly straight, slightly rounded in plane perpendicular to plane of figure, not visible in Figs 91-92; R 3 robust, widened caudally; R4 large, plate-like; R 5 in shape of cranially widened, long and thin strip, surrounded with membranous lobe. Sclerite L2D (L1) divided into basal and apical parts ( Fig. 93); basal part rod-like, weakly widened cranially; apical part in shape of flattened, elongated and plate-like sclerite ( Figs 93-95, ap.scl.), “dorsal outgrowth” small ( Figs 93-95, d.o.); bristles absent. Sclerite L3 (L2d) with basal subsclerite ( Fig. 98, b.L 3); “folded structure” distinct, with bristles; apex of L3 attenuated; groove hge present ( Figs 96-98, hge.). Sclerite L4U (L3d) present, weakly sclerotized.

Somatic characters of female: Brachypterous ( Fig. 100), body convex, surfaces of abdomen strongly sclerotized. General colour darker than male, blackish; colouration of head as in Fig. 9; pronotum and tegmina with wide lateral yellow strip ( Fig. 100); legs dirty yellow. Head with eyes and ocellar spots ( Figs 9, 99) smaller than in male; distance between eyes 1.2 times eye length; distance between antennal sockets 2.1 times scape length (~ 1.1 mm); approximate length ratio of 3rd-5th segments of maxillary palps 1.6: 1.0: 1.4. Pronotum campaniform, as in Fig. 100. Tegmina strongly abbreviated and malformed, as in Fig. 100; venation absent. Wings vestigial, completely hidden under tegmina. Fore tibiae not thickened distally. Anterior margin of fore femora of armed type C, with 2 apical spines. Tibial spines well developed. Structure of tarsi similar to those of male. Abdomen without visible glandular specializations. Anal plate (tergite X) wider than long, its hind margin widely rounded ( Fig. 101). Cerci strongly shortened, conical, with poorly visible traces of segmentation ( Fig. 101). Paraprocts medially membranous ( Fig. 103, par.), fused with anal plate, with membranous area at anteromedian angles ( Fig. 103, m.a.). Genital plate as in Fig. 102.

Ovipositor and adjacent structures ( Figs 103- 105): Intercalary sclerite absent. Tergal processes of abdominal segment VIII reduced ( Fig. 103, teVIII.); tergal processes of abdominal segment IX completely developed ( Fig. 103, teIX.). Gonangulum distinct, well sclerotized ( Figs 103-105, gg.). First valves of ovipositor large and membranous ( Figs 103-104, v.I.), with setae along inner side. Base of 2nd and 3rd pairs of valves as in Fig. 105, sclerotized lobes of irregular shape ( Figs 103-105, pl.). Anterior arch of second valvifer as in Fig. 105, a.a. Second valves of ovipositor small, completely hidden under first ones ( Fig. 104, v.II.). Third valves of ovipositor (gonoplacs) wide, partly membranous ( Figs 103-104, v.III.). Basivalvulae in shape of two small and weakly sclerotized plates ( Figs 103-104, bsv.). Vestibular sclerite weakly sclerotized ( Fig. 103, vs.). Brood sac ( Fig. 103, bd.s.) without sclerotized structures.
